Description
- The present invention relates to an aircraft.
- Currently, aircrafts capable of performing vertical take-off and landing are practically used.
- However, since functions of the vertical take-off and landing are realized by including mechanisms dedicated for vertical take-off and landing, there is a problem that structures thereof are more complicated and heavier than those of airframes of ordinary take-off landing-type aircrafts. Typical air frames for ordinary take off is disclosed in
FR419308A - There are problems that the mechanisms for vertical take-off and landing do not function at the time of ordinary flight, that tails thereof do not function at the time of vertical take-off and landing, and that heavy parts that do not contribute to flight are thus constantly included in the airframe.
- Also, since the airframes are adapted to perform flight control using different mechanisms at the time of vertical take-off and landing and at the time of ordinary flight, it is necessary to learn these two control methods in order to cause the airframes to fly.
- For these reasons, the airframes of vertical take-off and landing aircrafts cannot avoid a problem that mobility and cruising distance performance thereof are inferior to those of an ordinary take-off and landing type regardless of an increase in manufacturing, maintaining, and running costs as compared with the ordinary take-off and landing aircrafts.
- A problem to be solved is that current vertical take-off and landing aircrafts need two mechanisms and two different types of control for vertical take-off and landing and for ordinary flight.
- The present invention is characterized by the features as per
claim 1. - An aircraft according to the present invention has an advantage that since the aircraft does not have a mechanism and control dedicated for vertical take-off and landing even if the aircraft is a vertical take-off and landing aircraft, the aircraft has a simpler structure and can be manipulated by the same method as that of an ordinary take-off and landing aircraft that employs the present invention.

-
Figs. 1 to 14 illustrate an aircraft of an ordinary take-off and landing type of the present invention. -
Figs. 5 and6 are an airframe coordinate diagram illustrating a state of shoulderrotational axes 2 and armrotational axes 3 when the airframe is horizontally flying and a diagram of a spatial posture thereof when the airframe is flying in the state. The airframe horizontally balances the airframe and horizontally flies by causing the shoulderrotational axes 2 to rotate and settinglift force points 5 on the left and right sides of the airframe and a gravity center 4 of the airframe at the same positions in airframe coordinates Z, and adjusts directions of lift forces at thelift force points 5 generated in thewings 6 by causing the armrotational axes 3 to rotate. -
Figs. 7 to 10 are airframe coordinate diagrams illustrating a pitch control method of the airframe and diagrams of spatial postures thereof. Pitch control for lifting a nose is performed using an action, which is caused by causing the shoulderrotational axes 2 to rotate to move thelift force points 5 on both sides of the airframe to the front side of the airframe beyond the gravity center 4 of the airframe, in which the gravity center 4 of the airframe rotates using a straight line connecting both thelift force points 5 as an axis and tends to move and be stabilized below the straight line. Similarly, the nose is lowered by moving both thelift force points 5 to the rear side of the airframe beyond the gravity center 4 of the airframe. -
Figs. 11 to 13 are an airframe coordinate diagram illustrating a circling control method of the airframe and diagrams of spatial postures thereof. A rotational angle of one of the two shoulderrotational axes 2, whichever is located on the inner side at the time of circling, is reduced relative to a rotational angle of another axis located on the outer side to move thelift force point 5 located on the inner side of the circling to the front side of the airframe beyond thelift force point 5 located on the outer side, creating an inclination of the straight line connecting both thelift force points 5 with respect to an X axis, Y axis, and Z axis of the airframe coordinates. At this time, two types of control, namely nose lifting control and rolling control are achieved by a stabilizing action caused when the gravity center 4 of the airframe rotates about an axis with the inclination and tends to move below the axis. In addition, circling occurs such that yaw axis rotation about thewings 6 is controlled when thewing 6 on the inner side of circling with an increased angle of attack is decelerated due to air resistance because the rotational angle of the shoulderrotational axis 2 is reduced. -
Fig. 14 is an airframe coordinate diagram illustrating a rolling control method of the airframe. Rolling control is performed by causing the armrotational axes 3 to rotate in a bilaterally asymmetric manner and inclining the directions of the lift forces in a bilaterally asymmetric manner. -
Figs. 15 to 33 illustrate an aircraft of a vertical take-off and landing type according to the present invention. -
Figs. 18 and 19 are an airframe coordinate diagram of the airframe at the time of horizontal flight and a diagram of a spatial posture thereof. The second embodiment has no differences from the first embodiment in terms of the control method and is different from the first embodiment only in that apropeller rotation plane 8 is a lift force source of the airframe instead of thewings 6. -
Figs. 20 to 23 are airframe coordinate diagrams illustrating a pitch control method of the airframe and diagrams of spatial postures thereof. The control method is the same as that in the first embodiment. -
Figs. 24 and26 are an airframe coordinate diagram illustrating a circling control method of the airframe and diagrams of spatial postures thereof. This control method is the same as that in the first embodiment and is different therefrom only in that thepropeller rotation plane 8 rather than thewings 6 is an air resistance source used to obtain yaw axis rotation of the airframe. - The rolling control method of the airframe is also the same as that in the first embodiment.
-
Fig. 27 is a diagram of a spatial posture when the airframe is stopping in a space with the nose lifted. This pitch control is also the same as that in the first embodiment. -
Fig. 28 is a diagram of a spatial posture when the airframe rotates about the yaw axis while stopping in the space with the nose lifted. The yaw axis rotation control about the airframe is performed by causing the armrotational axes 3 to rotate in a bilaterally asymmetric manner and inclining the directions of the lift forces at thelift force points 5 in a bilaterally asymmetric manner. -
Fig. 29 is a side view ofFig. 28 . -
Fig. 30 is a diagram of a spatial posture when the airframe is going backward while stopping in a space with the nose lifted. The airframe goes back by causing the armrotational axes 3 to rotate in a bilaterally symmetric manner and inclining the directions of the lift forces at both thelift force points 5 on the rear side of the airframe. -
Fig. 31 is an airframe coordinate diagram when the airframe is moving in the lateral direction of the airframe while stopping in a space with the nose lifted. The rotational angle of the axis of the two shoulderrotational axes 2, whichever is located on the front side in an advancing direction at the time of lateral movement, is reduced relative to the other axis on the rear side to move thelift force point 5 located on the front side in the advancing direction to the front side of the airframe beyond thelift force point 5 on the rear side, creating an inclination of the straight line connecting both thelift force points 5 with respect to the X axis, the Y axis, and the Z axis of the airframe coordinates. At this time, nose lifting control and rolling control are achieved by a stabilizing action caused when the gravity center 4 of the airframe rotates about an axis with the inclination and tends to move below the axis. As a result, lateral movement occurs by using the inclination of the directions of the lift forces at thelift force points 5 in the lateral direction along with the airframe. -
Figs. 32 and 33 are diagrams of spatial postures inFig. 31 . -
Figs. 34 to 36 illustrate a vertical take-off and landing aircraft that employsclam 2 of the present invention and includes jet engines on thewings 6. The flight control method of the airframe is the same as that in the second embodiment. -
